1. An apparatus for sterilizing one or both of a medical device and bodily tissue adjacent to the medical device, comprising:
- a cylindrical sheath, extending from a sheath proximal end to a sheath distal end, including a sheath wall defining a sheath lumen, the sheath wall and the sheath lumen capable of receiving and transmitting a sterilizing light, wherein the sheath wall includes at least one channel comprising a longitudinal portion and a transverse portion, extending in a direction transverse to the longitudinal portion, the transverse portion including a port formed in an inner surface of the sheath wall, adjacent the sheath lumen, or an outer surface of the sheath wall;
a housing, surrounding the sheath proximal end, including a housing outer wall and a housing inner wall, the housing outer wall and housing inner wall defining a housing chamber there between, the housing inner wall defining a housing lumen, wherein the housing lumen and the sheath lumens are collinear and configured to receive a portion of the medical device; and
a sterilizing assembly including a light source electrically coupled to a battery, the light source and the battery located within the housing chamber.
